Digital Decluttering: 3 Ways to Visualize Your Mac’s Hard Drive

By:

How to spot RAM offenders, or what data visualization has to do with the workings of your second brain.

Our hard drives are our satellite brains, vital extensions of our intellectual and creative input and output. But our informationally voracious habits also mean that our second brains get inevitably overwhelmed, slowing down and spasming under the weight of our tastes and interests. To combat the issue, here are three fantastic visualization tools — playing on today’s running theme of data visualization — that help declutter your hard drive without requiring any programming knowledge, visually track down what takes the most space and memory, and allowing you to optimize accordingly.

GRAND PERSPECTIVE

GrandPerspective is a Mac OSX utility for graphically showing the file disk usage on your computer using tree map visualizations. It developed by Erwin Bonsma and is released for free as open-source under the GNU General Public License. You can support the project with a donation.

Direct download link.

DAISY DISK

DaisyDisk scans your hard drive, as well as any external drives you have mounted, and visualizes the contents as interactive maps, allowing you to easily spot unusually large files and delete or move them to an external hard drive to get more free space. The program’s scanning engine is surprisingly fast even with drives as large as several terabytes. You can get a copy for the rather reasonable $19.99.

DISK INVENTORY X

Disk Inventory X, developed by Tjark Derlien, is very similar to GrandPerspective — same tree map visualizations, also a free download and under a GPL license, also supported by donations — though with a slightly different and more intuitive interface. It was inspired by WinDirStat, the hard drive visualization utility for Windows.

Visualize This: How to Tell Stories with Data

By:

How to turn numbers into stories, or what pattern-recognition has to do with the evolution of journalism.

Data visualization is a frequent fixation around here and, just recently, we looked at 7 essential books that explore the discipline’s capacity for creative storytelling. Today, a highly anticipated new book joins their ranks — Visualize This: The FlowingData Guide to Design, Visualization, and Statistics, penned by Nathan Yau of the fantastic FlowingData blog. (Which also makes this a fine addition to our running list of blog-turned-book success stories.) Yu offers a practical guide to creating data graphics that mean something, that captivate and illuminate and tell stories of what matters — a pinnacle of the discipline’s sensemaking potential in a world of ever-increasing information overload.

And in a culture of equally increasing infographics overload, where we are constantly bombarded with mediocre graphics that lack context and provide little actionable insight, Yau makes a special point of separating the signal from the noise and equipping you with the tools to not only create better data graphics but also be a more educated consumer and critic of the discipline.

From asking the right questions to exploring data through the visual metaphors that make the most sense to seeing data in new ways and gleaning from it the stories that beg to be told, the book offers a brilliant blueprint to practical eloquence in this emerging visual language.

On the book’s companion site, you can find downloadable data files, interactive examples of how visualization works and, if you’re technically inclined, even code samples to use as the basis for your own visual experimentation.

Visually stimulating, intellectually illuminating and creatively compelling, Visualize This: The FlowingData Guide to Design, Visualization, and Statistics is equal parts practical vocabulary for an essential modern language and conceptual testament to the power of data visualization as a new form of journalism and a powerful storytelling medium.

For a historical perspective on infographics, be sure to see the story of Otto Neurath’s Isotype.

Nathalie Miebach’s Sculptural Soundtracks for Storms

By:

What stormy weather has to do with Stormy Weather and the cross-pollination of poetry and precision.

Visualizations of music, creative takes on notation and physical data art are all running fixations here at Brain Pickings. Naturally, the work of Boston-based artist Nathalie Miebach, one of this year’s crop of extraordinary TED Global Fellows, is an instant favorite. Miebach translates weather and climate change data from cities into musical scores, which she then translates into vibrant, whimsical sculptures and uses them as the basis for collaboration with musicians across a wide spectrum of styles and genres.

Musical notation allows me a more nuanced way of translating information without compromising it.” She uses these scores to collaborate with musicians across a wide spectrum of styles and genres.” ~ Nathalie Miebach

External Weather, Internal Storms

Reed, metal, wood, data | 2009

Musical Buoy in Search Towards a New Shore (Dedicated to Melvin Maddocks)

Wood, data, reed | 2009

Hurricane Noel

3D Musical Score of the passing of Hurricane Noel through the Gulf of Maine, Nov 6-8, 2007. Meteorological data comes from two weather stations in Hyannis, MA and Natashquan, Quebec as well as an off-shore buoy anchored on George's Bank in the Gulf of Maine. Data translated includes wind, air temperature, barometric pressure, wave height, cloud cover, historical hurricane data and solar azimuth.

Each sculpture not only maps the meteorological landscape of a specific time and place, but is also a fully functional musical score to be played and interpreted by musicans on instruments as varied as piano, French horn and electrican guitar. You can hear and download the resulting tracks on Miebach’s site.

She's Coming on Strong

9'x9'x1', paper, wood, data, 2011

This piece is a musical score that tracks the paths of both Hurricane Grace and the Halloween Storm, which together created the 'Perfect Storm'.

Miebach uses basket-weaving techniques and materials to interpret the data in three-dimensional space, using the lens of art and craft to look at scientific with new eyes and glean new understanding.

Urban Weather Prairies - Symphonic Studies in D

16’x15’x15’, reed, wood, data, 2009

Urban Weather Prairies is based on data collected in Omaha, Nebraska, during a 2-month period (May /June 2008), while I was an Artist in Residence at the Bemis Center for Contemporary Arts. I chose to translate the data I collected in the format of an orchestra as a way to more truthfully articulate the somewhat idiosyncratic way I was making sense of my daily weather observations. Just like each instrument in a symphony plays part of the score, each sculpture and wall piece tells part of the story, with the entirety of the piece coming together through the larger behavioral patterns that slowly emerge over time. The wall space uses the rectangle as varies maps of Nebraska or urban centers of Nebraska.

What I like about this work is that it challenges our assumption about what kind of visual vocabulary belongs in art versus science.” ~ Nathalie Miebach

Together, Miebach’s sculptures explore the fascinating intersection of art and science — another recurring theme here — with equal parts poetry and precision, making science more accessible and art more cerebral — a pinnacle of the cross-pollination of disciplines at the heart of Brain Pickings.

7 Essential Books on Data Visualization & Computational Art

By:

What 12 million human emotions have to do with civilian air traffic and the order of the universe.

I’ve spent the past week being consistently blown away at the EyeO Festival of data visualization and computational arts, organized by my friend Jer Thorp, New York Times data artist in residence, and Dave Schroeder of Flashbelt fame. While showcasing their mind-blowing, eye-blasting work, the festival’s all-star speakers have been recommending their favorite books on the subject matter, so I’ve compiled the top recommendations for your illuminating pleasure. Enjoy.

PROCESSING

Processing, the open-source programming language and integrated development environment invented by Casey Reas and Ben Fry in 2001, is easily the most fundamental framework underpinning the majority of today’s advanced data visualization projects. Processing: A Programming Handbook for Visual Designers and Artists, which Casey Reas called “the first substantial handbook on art in computer science,” is an elegant introduction to the Processing language, bridging the gap between programming and visual art. It’s an invaluable self-learning tool for the novice coder and a standby reference guide for the Processing practitioner.

WE FEEL FINE

Since 2005, (a longtime Brain Pickings favorite) have been algorithmically scrobbling the social web to capture occurrences of the phrases “I feel” and “I am feeling” harvesting human sentiment around them by recording the full context in which the phrase occurs. The result was a database of millions of human feelings, logged in the We Feel Fine project and growing by about 20,000 per day. Because the blogosphere is lined with metadata, it was possible to extract rich information about the posts and their authors, from age and gender to geolocation and local weather conditions, adding a new layer of meaning to the feelings. The project’s API, with nearly 7 years’ worth of data, is the most comprehensive record of human emotion ever documented.

In 2009, Sep and Jonathan published highlights from the project in We Feel Fine: An Almanac of Human Emotion — a remarkable visual exploration of the 12 million human emotions collected since the project’s dawn. Infographic magic and data visualization wizardry make this massive repository of found sentiment incredibly personal yet incredibly relatable. From despair to exhilaration, from the public to the intimate, it captures the passions and dreams of which human existence is woven through candid vignettes, intelligent infographics and scientific observations.

SYNC

In Sync: How Order Emerges From Chaos In the Universe, Nature, and Daily Life, Cornell mathematician Steven H. Strogatz explores the intersection of math, physics, quantum science and biology to unravel the mystery of how spontaneous order occurs at every level of existence, from the cell nucleus to the cosmos. The same principles that Christiaan Huygens observed in 1665 as two pendulum clocks to swung in unison and pedestrians experienced in near-hoor at the 2000 opening of the Millennium footbridge in London are the same principles that fascinate and drive many of today’s data visualization artists as they seek to discover and make visible the patterns and orders underpinning our world.

INFORMATION VISUALIZATION

Information Visualization, Second Edition: Perception for Design explores the art and science of why we see objects the way we do through an exercise in visual literacy that makes the science of visualization accessible and illuminating to a non-specialist reader, without dumbing any of it down. From the cognitive science of perception to a review of empirical research on interface design, the book covers a remarkable spectrum of theory and practice fueling data visualization as a design discipline and a visual language.

ART FORMS IN NATURE

Kunstformen der Natur (Art Forms in Nature), originally featured in his omnibus on biology-inspired art, is a remarkable book of lithographic and autotype prints by German artist and biologist Ernst Haeckel, originally published in sets of ten between 1899 and 1904 and as a complete volume in 1904. It features of 100 prints of various organisms, many first described by Haeckel himself. (You may recall Proteus, the fascinating short documentary about Haeckel’s work and legacy, featured here earlier this year.) The shapes, color theory and aesthetic of Haeckel’s work are the inspiration behind much of today’s generative art.

The copyright on the book has now expired and all the images are in the public domain, available for free on Wikimedia Commons.

BEAUTIFUL VISUALIZATION

Beautiful Visualization: Looking at Data through the Eyes of Experts examines what makes successful visualization through insights, perspectives and project case studies by 24 experts — artists, designers, design writers, scientists, statisticians, programmers and more. Above all, it explores the intricacies of visual storytelling through projects that tackle everything from civilian air traffic to the social graphs of Amazon book purchases, blending the practical with the poetic.

Contributors include Nick Bilton, Jessica Hagy, Aaron Koblin, Moritz Stefaner, Jer Thorp, Fernanda Viegas, Martin Wattenberg, and Michael Young.

MATERIAL WORLD

The work of photojournalist Peter Menzel (of Hungry Planet and What I Eat fame) broadens the definition of “data visualization” though the lens of the humanities, offering compelling visual anthropology captures the striking span of humanity’s socioeconomic and cultural spectrum. His Material World: A Global Family Portrait is an engrossing visual portrait of the world’s possessions across 30 countries, captured by 16 of the world’s leading photographers. In each country, Menzel found a statistically average family and photographed them outside their home, with all of their belongings. The result is an incredible cross-cultural quilt of possessions, from the utilitarian to the sentimental, revealing the faceted and varied ways in which we use “stuff” to make sense of the world and our place in it.

China: The Wu Family

The nine members of this extended family live in a 3-bedroom, 600-sq-foot dwelling in rural Yunnan Province. They have no telephone and get news through two radios and the family's most prized possession, a television. In the future, they hope to get one with a 30-inch screen as well as a VCR, a refrigerator, and drugs to combat diseases in the carp they raise in their ponds. Not included in the photo are their 100 mandarin trees, vegetable patch, and three pigs.

United States: The Skeen Family

Rick and Pattie Skeen's 1,600-sq-foot house lies on a cul-de-sac in Pearland, Texas, a suburb of Houston. Rick, 36, now splices cables for a phone company. Pattie, 34, teaches at a Christian academy. Photographers hoisted the family up in a cherry picker to fit in all their possessions, but still had to leave out a refrigerator-freezer, camcorder, woodworking tools, computer, glass butterfly collection, trampoline, fishing equipment, and the rifles Rick uses for deer hunting, among other things. Despite their possessions, nothing is as important to the Skeens as their Bible -- an interesting contrast between spiritual and material values.

Japan: The Ukita Family

43-year-old Sayo Ukita had children relatively late in life, like many Japanese women. Her youngest daughter is now in kindergarten, not yet burdened by the pressures of exams and Saturday 'cram school' that face her nine-year-old sister. Sayo is supremely well-organized, which helps her manage the busy schedules of her children and maintain order in their 1,421-sq-foot Tokyo home stuffed with clothes, appliances, and an abundance of toys for both her daughters and dog. Despite having all the conveniences of modern life, the family's most cherished possessions are a ring and heirloom pottery. Their wish for the future: a larger house with more storage space.

Mali: The Natomo Family

It's common for men in this West African country to have two wives, as 39-year-old Soumana Natomo does, which increases their progeny and in turn their chance to be supported in old age. Soumana now has eight children, and his wives, Pama Kondo (28) and Fatouma Niangani Toure (26), will likely have more. How many of these children will survive, though, is uncertain: Mali's infant mortality rate ranks among the ten highest in the world. Possessions not included in this photo: Another mortar and pestle for pounding grain, two wooden mattress platforms, 30 mango trees, and old radio batteries that the children use as toys.
